The Kozy Coats Experiment
2009-03-28: Ta-da! Today was the Day!
Last weekend, took out the kozy coats (and some new Aqua Shields from Home Depot) and tried 'em out. The kozy coats are great. The aqua shield leaked, so 5 of the tubes went flat...
Oh, well. It still works, ish.
In any case! The weather forecast looks good, and the 6-week-old tomato plant was way overdue for planting out! So put together my newest growbox, and set out my first victim! 
The tomato looks pretty scrunched and whiny in there. It's too tall and wide to have the teepee closed over its head, but tough. For the first few days, I think it needs the warmth of having the kozy coat closed on top. Later I can fill the tubes higher and make the walls stand up straight.
Still working on the next tomato (Buck's County Hybrid) and cantaloupe / cucumber / pepper seedlings. And still have a backup Early Girl tomato plant to replace this one with, if it doesn't do well. In the future, I think tomatoes should have a max 4 week head start for these igloos, not 6-8 weeks. And peppers max 6 weeks.
The hope is that the driveway is warmer / more sheltered than the 3rd floor balcony this time of year.
2009-04-12: Installed 3.5-week Bucks County tomato and 3-week Japanese cucumber (seed souvenir from Japan), and 2-week Cucumber Pearl in kozy coats. (The cukes share one.) Plus 2 Sweet'n Early cantaloupe (aged 3 and 2 weeks) sharing an aqua shield. Set up pot and aqua shield for 3-week Supertasty tomato, but didn't transplant out yet - checking for leaks first.
2009-04-14: The two newer aqua shields aren't leaking, so planted my 3-week supertasty tomato. Since the 6th water igloo doesn't hold enough water to really work, this completes the experiment setup.
Lessons learned:
- Kozy coats are better quality than aqua shield.
- 2 to 4" seedlings are best. That's a 3-4 week tomato or pepper, not the 6-8 weeks you'd grow for normal-season planting out. You want the seedling entirely inside a fairly short cone, which doesn't work well if the plant is already branched out.
- The instructions that should have come with the things.
- Magenta and aqua together are an eye sore. Wall'o'water may be worth a try, and look better.
2009-05-10: Further conclusions below. Tracking the plants from here by type in new topics, will comment back here when get harvests (as to whether they mattered in the end.)
2009-05-17: Peeled kozy coat off Early Girl biggest tomato plant before it could do any more disruption by removing it. Caged the tomato. (To get it off, sort of rolled it over to squeeze out water until only a donut shape was left, then pulled it off. Would've been better to have an assistant, since the tomato plant fell over in the process.)
2009-05-23: This week, removed kozy coat from Supertasty tomato, wall o' waters from cantaloupes and peppers. Only teepees still in play are kozy coats on Bucks County tomato and eggplant twinkle.
2009-07-09: Harvested first ripe, golf-ball sized Early Girl tomato. Not terribly early...
Rummaging around, I ran into the instructions that should have come with the kozy coats and aqua shields, but didn't.
Says several things I already learned the hard way, like to start 3-4 week old peppers and tomatoes for them, not 6-10 week. Just went out and squeezed the Early Girl tomato kozy coat column back into a cone. Better off warm and scrunched.
Fortunately, this sacrificial victim practice tomato is still alive and well, and still looks capable of producing tomatoes eventually.
This really is a point that should have been included in the instructions. It's not as though you can pick up tomato plants at the supermarket out of season. Of course you had to start them yourself, N weeks before outset. 
Today installed 3.5-week Bucks County tomato and 3-week Japanese cucumber (seed souvenir from Japan), and 2-week Cucumber Pearl in kozy coats. (The cukes share one.) Plus 2 Sweet'n Early cantaloupe (aged 3 and 2 weeks) sharing an aqua shield. Set up pot and aqua shield for 3-week Supertasty tomato, but didn't transplant out yet - checking for leaks first.
The Bucks County tomato got accidentally run over with its kozy coat.
Looks OK, hopefully it'll recover... It's a little challenging to work with a couple gallons of water in floppy tubulur form.
Because half the tubes in the first aqua shield leaked, I'm making sure both aqua shields hold water properly before committing the Supertasty tomato. It can wait a week if need be. The last guinea pigs contenders in this experiment are two peppers, that are still working on their first true leaves.
So. In an ideal world, if this works perfectly, we hope for time out early to count as at least 1/2 time toward earlier fruit. I grew the white cukes and supertasty tomato last summer.
The two aqua shields I set up Sunday are holding water, so planted out my 3-week-old supertasty tomato today.
The Early Girl tomato (first in kozy coats, oversized) looks wet and scrunched, but is developing flower buds. The Bucks County tomato doesn't look any different than when I planted it two days ago, which is good. The cucumbers and melons have visibly grown in two days.
The nearby spinach has also visibly grown. It really likes the growbox fertlizer. 
That kinda completes the kozy coats plant array. I have some peppers to put out later, but the last igloo isn't structurally sound. So I might put out the peppers early with the broken aqua shield rigged as sort-of protection, but it won't count toward how well they work.
So, if all goes well, I should get ripe tomatoes and cukes and melons by June, right?
Well, cukes anyway.
2009-04-18: Well... the aqua shields don't leak, but their seams are getting sprung, so they turn into waterbags at the bottom.
Ordered another 3... because I'm stubborn. And I'm afraid if they keep going this way, my cukes and melons won't make it, and they're cute.
The red kozy koats are definitely better... The new 3 I ordered are Burpee wall o water's. Which hopefully aren't the same thing as the Burpee Aqua Shield.
All the plants look like they're growing well. The Early Girl tomato has buds already, and it's probably safe by now to pollinate them and let them fruit. If I can. There will be more frosts, but not hard freezes, I think. And even with the teepee open, a light frost shouldn't hurt it.
2009-04-24: I succumbed to temptation and bought wall o water's too.... Because I didn't trust the aqua shields - which leaked and had seams sprung - to last. I'd also hoped the wall o waters were clear instead of aqua, as in the picture at Burpee.com, but, they're aqua. But - clearer. 
Anyway, replaced sprung aqua-shield on cantaloupes with a new wall o water, planted out my baby peppers (banana and mariachi) in a second wall o water. Swapped red for aqua between cucumbers and supertasty tomato. And put my twinkle eggplant out in a retired aqua-shield, just sitting on the driveway.
The cucumbers look done for. I'm not sure whether it was a) a really bad idea to spray fungicide on them because I was afraid of powdery mildew, b) was very cold last night and the teepee wasn't tightly closed enough, or c) was very warm today, they may have just wilted in there temporarily. Soaking new cucumber seeds, anyway... The cantaloupes aren't showing much progress, either. These things just don't grow until they're hot.
The supertasty tomato looks happy. The Bucks County... is growing at glacial speed. The Early Girl is starting to pop out of the kozy coat, which will be great for this weekend (freak summer temps), but might be a little early in the long run.
Added the 8-week-old twinkle eggplant to the kozy coats experiment after all, since I have extra teepees now...
This guy's the same age as the younger eggplant in my pro100, but a bigger variety (24" tall twinkle vs 12" tall bambino). Its soft furry leaves are now growing thorns down the top center leaf veins. Isn't that cunning... ow.
I like these little Kozy Coats, they make me smile as I can see them as some kitsch 1970's type light shade.
Just need a little wire structure inside and voilà!
, Peat.
They are kitschy. I was disappointed the wall o waters weren't clear like they looked in the burpee.com photo. I think I'd get greater acceptance from my neighbors with clear & magenta. The aqua & magenta combo on a terracotta pot is rather an eyesore.
We'll see how long I get away with it before people start kvetching.
Mixed week for the growboxes. On the downside, my cukes and one of the cantaloupes failed. Which was expected, and why I planted some more.
On the upside, the Early Girl tomato began flowering!
Normal conventional wisdom around here is that you don't put summer annuals out before Mother's Day (next weekend), and on a cold winter like this one... maybe Memorial Day weekend (end of May). And then an Early Girl should take 2 more months (~60 days) to harvest after transplanting out. So it is quite a ways ahead. Though now that it's hanging out the top of the kozy coat, I need to put a trash bag over it on cold nights. No freezes in the 2-week forecast, but several nights in the 30's, including tonight.
Gisette,
Good looking tomato plant. I've got flowers on my earthbox planted polefast tomato - it isn't very happy with the weather. Are you having this cool rainy weather like we're having? Driving me nuts! I did manage to get some strawberries planted on Friday. They're liking the rain.
Beth
Beth - I imagine we're having cooler rainy weather than you're having.
I think we're finally past 30's at night (just as of Sunday...) and into 40's at night, 50's and 60's during the day. Everything took off during a 4-day heatwave last weekend, and the world is green, trees blooming and starting to leaf. Pretty! But overall temps are still pretty low.
I think I'm gonna switch to by-crop-type for my growlog pictures of these things.
Conclusions on the kozy coats so far:
- Clear win for the eggplant and tomatoes. One tomato plant not doing so well, but it wasn't that healthy going in.
- Need to apply differently for cukes and melons. One plant in mid-teepee might work, 2 at the edge didn't. Besides, the teepee isn't enough to provide the kind of heat cucurbits crave.
- Peppers (2 at the edge) are probably getting a good start with the wall o water, but not as clear a win.
- They'd work better on full-sun garden soil than on part-day sun containers. A water teepee on ground can really set the soil temperature. Not so on a container. And the limited floor space on a container prevents the teepee from forming the right shape. The Growbox exacerbates this because plants are placed at the sides, not the middle. Plants don't much like being squished against a cold drippy plastic wall, and they do get very wet inside in CT spring.
On the water teepee products themselves:
- The Burpee AquaShields failed to hold water properly, on 3 out of 3. Do not buy.
- The Kozy Coat claim that the red made for a nice stocky tomato plant seems to be true. Good quality.
- The aqua (not clear as pictured on Burpee site) Wall o Waters also seem good quality, hold water properly, but the plants in them haven't done as well. But I've had the Walls less time, on more heat-craving plants, so... experiment not conclusive.
Edit: added comparative product verdicts.
Edit: realized later that the problem that led to my dead cucurbits was a misunderstanding on my part.
The seed leaves turned shock white, and I thought it was a fungus, and it was my treatment for fungus which actually led to their deaths. But it seems the white seed leaves are simply due to cold, and so far as I can tell, the true leaves aren't harmed. So... The plants might have done fine if I'd just let them be. Conclusion above still good, though - better to keep the seedlings off the teepee walls.
For what it's worth, I just searched on cucumber seed leaves turning white - the original problem that led me to kill my original cukes, and possibly one of the cantaloupes.
It just means they got too cold... So, if I hadn't tried to do something about them turning white, they probably would have been fine. (The true leaves weren't sick.)
Another case of plants thriving better on neglect. 
Another case of plants thriving better on neglect
I have come to believe that too.
Enjoy!
Well, I think I can come to a confident verdict now on cucurbits in kozy coats:
Don't bother.
It depends on local climate, how quickly your local weather goes from 50's to 70's. The kozy coats might allow one to take advantage of freak early springs or something. But here in shoreline Connecticut, freak hot days aside, spring is not sudden. I live by a giant bath tub named Long Island Sound. It warms up, and cools down, s l o w l y. And a long head start doesn't appear to do cucurbits any good whatsoever. When it's hot, they grow and fruit. When it's not, they wait. So, the standard advice is really as fast as they'll bear - plant seeds when last frost is past and soil begins to warm.
So, we really need Judith and Peat to succeed with their ag cuc grow! I want year round cucs!
Year-round cukes would be nice!!!
Such a convenient supper veggie, too. 
I was thinking the kozy coat thing maybe wasn't worth doing, because I was harvesting my Supertasty toms by this time last year, anyway.
But I've already harvested over 40 Early Girl and kibits tomatoes. Last summer by this time I had 4 total. And this summer's been dreadful tomato weather. Cold excessive rains until July, then epidemic late blight set in before July's end. Today one person told me my tomatoes were the first ripe ones he's seen this year. Later a neighbor whose tomatoes are rightly admired, told me he envied mine. He planted eighteen this year, and already thirteen have died, and his overall harvest has been 20 fruit. Now I'm fighting the late blight, and seem to be winning, much as that battle can be won. But the basic rule of thumb for late blight is, if you can see it, it's already too late, your plants are goners.
So... without the kozy coats, I may have gotten no harvest at all.

Hard to tell how the Early Girl tomato is doing inside its kozy coat, aside from it looking crowded. Not ill, nor growing at any great rate. Filled up the tubes so it's more column than teepee, since the plant looked so severely squashed in there. The backup tomato plant has been looking far less healthy, so hopefully this one will work out.
Still working on the melon, cucumber, and Bucks County tomato seedlings. This is the 2-week tomato seedling I almost tossed. It's been sitting outside in a kozy coat mostly (sort of quarantine), but looks like it's regaining its health, so coddling it today to see what happens. Its replacement still hasn't germinated.
